waiting time

Why does it take so long to load every time? It takes forever or doesn't work at all. I only see the same image for minutes at a time.

[bug?] Low FPS by blocks/tiles

So, i have interesting observation about that. I've low FPS on enough good PC, and low FPS caused by tiles/blocks rendering, on elevated platforms and fly i've good performance... I tried almost everything of listed in tmodloader github page, also tried disable SMT to force CPU to use only thread per core, just nothing, helped only tile rendering optimization from "high FPS support", but it's buggy and not enough for good performance, also i know about one-thread in-game engine, most load comes out from CPU, GPU works good on any cases, integrated GPU disabled on BIOS... PC specs...

Tmodloader wont open

Everytime i try to open the game, the usual black window appears, but then gets stuck and doesnt procede to open the game or close the window. there is no error message or anything so i dont know what is the problem, it just wont open. i tried to erase data, re-install the game many times, reset my computer. still the same error. no mods loaded. edit: also, by some reason i cant upload the "tmodloader-logs" archives, discord says there is an error and i should upload it later...

Game freezes and crashes when I try to summon Dragonfolly

I try using the Exotic Pheromones in the Jungle, then the game freezes, followed by crashing. I don't understand why. I'm posting this report to this server because I don't know what mods are specifically causing this issue.

I am unable to be killed by any means

No matter if its lava, fall dmg or basic mob, i just can't die, my hp goes to 0, sometimes even -X. I wanted to play Calamity Catalyst mode + few else from Calamity but found out i just cannot die, i tried dissabling every Cal mod but it does not worked same went with fargos and else, no tombs/shorter respawns mod also doesnt cause it and rest of mods i have doesn't really interacts with my death by any means. I have no clue how to fix that, I can show my mods that are enabled.

Mod help

I don't know if there's already a post for it but I was wondering if anyone can help me figure out why I can only get some of my mods to read on a gportal server. I read how to do it but can only get 4 to read/work and don't know what the next step would be. Any help is appreciated.

Terraria Collector's Edition not activated

I have the collector's edition and I created a character, and there was no carrot pet item. Thinking it may have been overwritten by another starter item, I grabbed one from an all items world, but upon equipping it it did not work, as if I did not have the collectors edition activated (which I do as it works as intended on vanilla on the same device) Tmodloader version is 2025.2.3.2, Terraria version is 1.4.4.9, and I am running both as native linux versions on Debian 12 I think it may be that tmodloader does not check for collectors edition activation, or that it does not check in the same place that vanilla checks (~/.mono/registry/CurrentUser/software/terraria/values.xml)...

Moving lags the game after moving after playing for a while with mods enabled on vulkan gldevice.

Whenever I'm in a world, after a random amount of time, moving the player & the mouse causes the game to lag, it also causes the title screen to lag when moving the mouse.
